OlL-BURNEFT FOR HEATING PURPOSES.

SPECIFICATION formingpart of Letters Patent No. 670,660, dated March '26, 1901.

Application filed April 28, 1898. Renewed August 25, 1900. $erial No. 28,087. (No model.)

To all, whom it may concern:

Be it known that I, CASPAR BLUMER, a citizen of Switzerland, residing at the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented a new and Improved Oil-Burner for Heating Purposes, of which the following is full, clear, and exact description.

One object of my invention is to provide a simple, durable, and economic form of burner adapted to utilize crude petroleum or other inflammable liquid as fuel and so constructed as to overcome all danger of explosion either at the burner itself, at the supply-pipes leading to the burner, or at the tan k or reservoir from which the said pipes are supplied, no valve being employed.

A further object of the invention is to provide a device for making use of liquid fuel that can be safely employed wherever it has been customary to burn wood, coal, or other hard fuel, being especially adapted for use in connection with boilers and for other heating purposes.

Another object of the invention is to so construct the device that the level of the fluid in the reservoir that supplies the burner and its connecting-pipes or the top of the reservoir itself is below the fire-line of the burner, although the reservoir may be remote from the burner.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in claims.

Referenceis to be had to the accompanying drawings, forminga part of this specification,

in which similar characters of reference indi-' made of any desired length and is in direct connection with the tubular shank B. The

tubular shank B is connected in a fluid-tight manner with an upright pipe 0 by means of a coupling D of any suitable construction. The upright pipe C, as shown, is connected by a horizontal pipe E with a tank or reservoir F, provided with a suitable top 10, and the burner at. a predetermined point between its ends is provided with a series of apertures 11, horizontally arranged. These apertures are draft-apertures, and the apertured surface of the burner may be provided with the customary apertured slides, so that the apertures maybe partially or entirely closed. Such slides have been omitted from the drawings, as they are of well-known construction.

The draft-apertures 11 are above the level of the top 10 of the tank or reservoir F, and the tank or reservoir F, the pipes E and O, the shank B of the burner, and the burner itself up to a point close to the opening 11 are filled as tightly as possible with a granulated absorbent material, preferably a mineral absorbent, the best results having been obtained by the use of granulated coal-ashes or of coke sifted free from dirt. The coal-ashes or the coke must have been well burned in order to readily absorb oil. Oil is supplied to the reservoir until all of the absorbent material has taken up or held in suspension as much oil as possible, and the oil thus absorbed by the absorbent material is efiectually prevented from exploding, while it will burn freely at the fire-line of-the burner, the gases being mingled with the air entering at the apertures 11. It will be understood that instead, of an ordinary Wick the lamp is provided with an absorbent wick, which completely fills it, the supply tank or reservoir, and all of the connections between said supply tank or reservoir and-the burner.

In order that the flame shall be spread, and thus promote combustion, a deflector 13 in the shape of a disk is supported, for exam ple, by legs or brackets 14 at a predetermined point above the fire or flame line of the absorbent material, a space intervening the edge of the deflector and the adjacent inner face of the burner. In order to regulate the size of the flame, a damper 15 is employed, which passes through one side of the burner and is held to slide in ways 16, located within the burner, as shown in the drawings.

The flame will be instantly extinguished when the damper is pushed inward sufficiently to prevent communication between the top of the burner and the fire or flame line of the absorbent material.

In Fig. 2 I have illustrated a burner constructed for adaptation to a horizontal boiler. The burner is constructed as heretofore described, with the exception that the deflecting-disk 13 is carried to a point at or near the top of the burner, and a hood 17 is secured at the top of the burner and of elbow form, whereby the flame or products of combustion may be conducted directly to the tube-sheet of the boiler.

In all boilers the burner is placed in the ash-pit, and the ash-pit is suitably prepared to admit snflicient air to the burner.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. Thecombinationfin a burner, of a body having draft-openings, a deflector, and a damper between the draft-openings and deflector.

2. A burner having draft-openings, a deflector above the draft-openings, and a damper between the draft-openin gs and deflector,
